Profile, Sonic the Hedgehog 4: Episode I website

The Newtron (メレオン Mereon?) is a recurring enemy in the Sonic the Hedgehog series. They are chameleon-based Badnik models created by Dr. Eggman which first appeared in Sonic the Hedgehog (1991). Usually coming in two types, the Newtrons can camouflage themselves.


Newtrons are based on chameleons. Newtrons have a head, a stripy tail and four white feet with three fingers. One of these fingers are backwards so the Newtrons can get an extra grip. They also have yellow eyes with small pupils and a brown and sharp parietal crest. Newtrons come in two color varieties: green and blue. The green variation has yellow eyes and the blue varitation has red eyes.

Newtrons in Sonic the Hedgehog 4: Episode I are more smooth and have detailed limbs. In Sonic Generations though, they are more mechanical and both varieties has cyan eyes. Newtrons in Sonic Lost World are slightly smaller than previous models and have cyan eyes with yellow sclera.

Powers and abilities

Newtrons can camouflage themselves accordingly to the wall they are on and phase out of sight when they see their target. They have also different methods of attack depending on their colors:

  • The green Newtron, after becoming visible, spits a ball of energy at the player before turning invisible again. It never moves from its wall though.
  • The blue Newtron, after becoming visible, drops from the wall and morphs into a chameleon-shaped rocket, which chases Sonic in a fixed horizontal line. The blue variety is easier to deal with as it can be attacked, unlike most of its green counterparts. Green Newtrons in Sonic the Hedgehog 4: Episode I however, are also able turn into rockets as well.

Game appearances

Sonic the Hedgehog (1991)


Newtrons make their first appearance in the original 16-bit version of Sonic the Hedgehog. Both varieties appear in the Green Hill Zone. Both of them can be destroyed with Spin Jump as they starts to appear on the wall. Green variants can shoot energy balls from the walls at Sonic, whereas blue variants will jump off the walls and attack the player directly. On some occasions, the player is unable to destroy green Newtrons depending on their placement in the Zone.

In 8-bit version of the game with same name, only the green variation of Newtrons appear at Jungle Zone, although they have the same attack patterns as their 16-bit counterpart. However Newtrons do not have Animals inside of them as power source like many other Badniks in the Master System and Game Gear titles.

Sonic Lost World

In Sonic Lost World, the Newtrons regain their original design, although they are smaller. During the game, it turns out that the Badniks, the Newtrons included, got hijacked by the Deadly Six.

Green type Newtrons appear in Windy Hill Zone 1 and Sky Road Zone 1 in the Wii U version, and in Windy Hill Zone 1-2 in the Nintendo 3DS version. Green Newtrons mostly have the same attack patterns as in Sonic the Hedgehog (1991), as they turn invisible, hang on walls and shoot small projectiles at the player. These Badniks can be defeated by using the Focused Homing Attack. In this game, they again contain Animals inside of them.

In the Sonic the Comic series published by Fleetway Editions, the Newtrons were standard models in Dr. Robotnik's Badnik army. In this media, they lacked any form of projectile weapons and cloaking ability, and were more akin to melee fighters. Depending on the artist, the Newtrons' design would differ between issues. Earlier models of Newtrons were also quadruped, but later models became bipedal.

The Newtrons got decommissioned after the occurrence of an electromagnetic pulse which affected the planet Mobius.

Archie Comics
